Procedure

A mixture of ethyl 2-(3-chloro-4-iodo-5-(2,2,2-trifluoroethoxy)phenyl)-3-cyclopropylpropanoate (1.1 g, 2.4 mmol), 4-trifluoromethylphenylboronic acid (0.928 g, 4.9 mmol), CsF (0.926 g, 6.1 mmol) and Pd (PPh3)4 (0.283 g, 0.245 mmol) in 50 mL anhydrous 1,2-dimethoxy ethane was refluxed for 8 h under argon. The reaction mixture was cooled, and 40 mL of EtOAc and 40 mL of water were added. The organic phase was separated, dried over Na2SO4, filtered and concentrated under reduced pressure to give a yellow oil. The oil was purified by column chromatography over silica gel (hexane/EtOAc, 95:5) to give ethyl-2-(2-chloro-6-(2,2,2-trifluoroethoxy)-4′-(trifluoromethyl)biphenyl-4-yl)-3-cyclopropyl propanoate (0.650 g) as a yellow oil.
